I think the Polygon class gets inherited by the Square class and the preview dont show any errors. Please help.

I think the Polygon class gets inherited by the Square class and the preview dont show any errors. I can not find the right path to solve this problem. Pls help.

Polygon.cs 
namespace Treehouse.CodeChallenges
{
    class Polygon
    {
        public readonly int NumSides;

        public Polygon(int numSides)
        {
            NumSides = numSides;
        }
    }
}

namespace Treehouse.CodeChallenges
{
    class Square : Polygon
    {
           public readonly int SideLength;

           public Square(int sideLength) : base(numSides);
           {
                SideLength = sideLength;
           }
    }
}

You're pretty close:

  • you don't need a separate "namespace" block, both classes can share the same one
  • in the constructor, the literal value of "4" needs to be passed to the base (for it to set "NumSides" with)
  • there should not be a semicolon on the line that declares the constructor
